Problem: Clumping in Formulations

Solution:

• Use a high-shear mixer when incorporating HEC into formulations to ensure even dispersion.
• Pre-hydrate HEC by mixing it with a small amount of cold water before adding it to larger volumes.

Problem: Inconsistent Viscosity

Solution:

• Control the concentration of HEC in your formulation.
• Monitor pH levels as they can affect viscosity; adjusting the pH may yield more consistent results.

Problem: Difficulties in Dispersal

Solution:

• Gradually add HEC while mixing to avoid lumps.
• Utilize hot water or a pre-solubilized version to improve dissolving rates.
